Effect of mobility on the performance of GA-based QoS routing in mobile ad hoc networks

The problem of QoS routing for MANET posses several challenges that must be addressed. To select the most optimal route from source to destination, one has to choose from a set of routes with the corresponding quality of connectivity and resources. Node mobility demands an exceptional performance of the protocol. It needs to select the route with the longest residual node-pair connectivity lifetime simultaneously as other metrics of interest. QOSRGA (QoS routing using GA) was designed to select QoS route based on QoS metrics such as bandwidth, delay and node connectivity index (nci). We outlined the GA process and how its related parameters are chosen. In this paper we specifically depicts the effect of mobility on performances of QOSRGA protocol.
